SETTING: Intravenous drug users (IDUs) represent a high risk group for
dual human immunodeficiency virus (HIV) and tuberculosis (TB) infection.
Screening with TB skin testing has therefore been suggested in this
group. Subjects' compliance for returning to have TB skin test results
read is a major problem. In the setting of a needle exchange program we
evaluated the role of financial incentives to increase compliance.
METHODS: We evaluated the role of giving a small financial incentive of
Can $5 to subjects if they returned to have their purified protein
derivative (PPD) skin test read. IDUs who had previously been
skin-tested were compared with IDUs drawn from a similar population who,
prospectively, were offered a financial incentive. RESULTS: During the
initial period 558 subjects were evaluated and no incentive was offered.
During the second phase of the study 549 IDUs were assessed but were
also offered Can $5 if they returned to have their skin test read. Use
of incentives increased compliance from 43% to 78% (P = 0.001). During
the same period three active cases of TB were also diagnosed.
CONCLUSIONS: We suggest that use of financial incentives can increase
the return of IDUs to have their skin tests read. Further studies are
required to assess the efficacy of follow-up interventions, especially
the use of isoniazid chemoprophylaxis.
